Abstract

Seit ein paar Jahren postuliert die DFG in ihren Praxisregeln "Digitalisierung", dass eine ausschließliche Bilddigitalisierung nicht mehr den wissenschaftlichen Ansprüchen Genüge leiste, sondern der digitale Volltext notwendig sei, da dieser die Basis für eine wissenschaftliche Nachnutzung darstellt. Um ein besseres Verständnis davon zu erlangen, was sich hinter dem Begriff "Volltext" verbirgt, wird im Folgenden ein kleiner Einblick in die technischen Verfahren zur automatisierten Volltexterschließung von Retrodigitalisaten geboten. Fortschritte und auch Grenzen der aktuellen Methoden werden vorgestellt und wie Qualität in diesem Zusammenhang überhaupt bemessen werden kann. Die automatisierten Verfahren zur Volltexterschließung werden am Beispiel historischer Zeitungen erläutert, da deren Zugänglichmachung gerade in den Geisteswissenschaften ein großes Desiderat ist und diese Quellengattung zugleich aufgrund der Spaltenstruktur besondere technische Herausforderungen mit sich bringt. 2016 wurde das DFG-Projekt zur Erstellung eines "Masterplan Zeitungsdigitalisierung" fertiggestellt, dessen Ergebnisse hier einfließen.

Abstract

Explores the potential of text analysis as a tool in full text search and design improvement. Reports on a trial analysis performed in the domain of family history. The findings offered insights into possible gains and losses in using one search or design strategy versus another and strong evidence was provided to the potential of text analysis. Makes search and design recommendation

Abstract

Examines how techniques in the field of natural language processing can be applied to the analysis of text in information retrieval. State of the art text searching programs cannot distinguish, for example, between occurrences of the sickness, AIDS and aids as tool or between library school and school nor equate such terms as online or on-line which are variants of the same form. To make these distinction, systems must incorporate knowledge about the meaning of words in context. Research in natural language processing has concentrated on the automatic 'understanding' of language; how to analyze the grammatical structure and meaning of text. Although many asoects of this research remain experimental, describes how these techniques to recognize spelling variants, names, acronyms, and abbreviations

Abstract

Dow Jones Interactive Publishing has developed a sophisticated automatic knowledge indexing system that will allow searchers of the Dow Jones News / Retrieval service to get highly targeted results from a search in the service's Publications Library. Instead of relying on a thesaurus of company names, the new system uses a combination of that basic algorithm plus unique rules based on the editorial styles of individual publications in the Library. Dow Jones have also announced its acceptance of the definitions of 'selected full text' and 'full text' from Bibliodata's Fulltext Sources Online directory
